| heal.abstract | A method for screening Sr-90 in milk samples is proposed. This method is based on a liquid scintillation technique taking advantage of Cherenkov radiation, which is produced in a liquid medium and then detected by the photomultipliers of a Liquid Scintillation Counter (LSC). Twenty millilitres of water and milk samples spiked with various concentrations of Sr-90/Y-90 in equilibrium were added in plastic vials and then were measured with an LSC (TriCarb 3170 TR/SL). The derived efficiencies were 49% for water samples and 14% for milk samples. The detection limit was 470 mBq L-1 Sr-90 for water, without any pretreatment. Milk contains potassium, which also produces Cherenkov radiation due to the presence of 411 K. For this reason, the interference of K-40 in the measurements of Sr-90 in milk samples was also investigated. The detection limit for milk was 1.7 Bq L-1 Sr-90. (c) 2006 Elsevier Ltd.
